Powered Up! A STEM Approach to Energy Sources

Earth?s population has increased from about 1 billion people in the early 1800s to more than 7 billion people in 2015. During this time, energy use also increased dramatically. In the last 40 years alone, the average amount of energy used by each person has tripled. This increased demand has led scientists to look into cleaner, more sustainable energy sources than the nonrenewable fossil fuels that have traditionally powered our planet. This exciting series explores alternative energy sources, including hydroelectricity, nuclear power, and geothermal energy. By learning about the pros and cons of using alternative energy sources, students will be able to make assessments about their future use as Earth?s energy needs continue to change.
